Since 2021

Against the 2021 result on these boundaries, the Liberals are up 19.6 (36.6% to 56.2%), the Conservatives up 3.1 (33.9% to 37.0%) and the New Democrats down 17.2 (22.7% to 5.5%), in points of the valid votes.

2021 is Elections Canada's transposition of that election onto the 2023 boundaries, not an election held on these lines.

The Liberals were first at six of the eight general elections from 2004 to 2025, the Conservatives at two; it changed hands twice. In 2025 the Liberals took 56.2% of the vote here, 17.5 points above their average of 38.7% at the seven general elections from 2004 to 2021.

On today's boundaries the Liberals were first here in 2004 (45.5%), 2006 (37.7%), 2015 (45.8%), 2019 (43.0%), 2021 (36.6%) and 2025 (56.2%) and the Conservatives in 2008 (39.1%) and 2011 (44.5%), each with the share of the valid votes shown.

A stronghold is a party first at every general election since 2004, by an average of 20 points or more over the next party; held, first at every one; usually, first at all but one. By-elections are not counted. By this rule 160 of the 343 ridings have no degree. The results before 2021 are carried onto today's boundaries by where the riding's 2025 electors lived: our estimate, from the older boundaries of Taylor, Lucas, Kirby and Hewitt and the results in Sevi's "Who Runs?". 2021 is Elections Canada's transposition, and 2025 the official result.

IDid this riding change?

Yes — it shrank. All of today's London West, its electors as well as its ground, comes from the old London West, but it is only 81% of that riding by area. The rest went elsewhere.

How this is measured. Electors: the share of the current riding's 2025 ordinary-list electors who lived in each former riding, each 2025 polling division placed in the 2013 riding a point inside it falls in. Area: the share of the current riding's area that came from each former riding, by intersecting the 2013 and 2023 boundary files, and how much of the former riding that part was. Area is land, not population. Elections Canada counts 48 of 343 ridings as entirely unchanged.

The 2021 column is Elections Canada's official transposition of the 2021 result onto these 2023 boundaries. ± is the change in each party's share. It is not "swing": with four or more competitive parties there is no single pair to swing between.

IIIHow close was it, really

New Democratic took fewer than the 12,070-vote margin.

Flip the seatHypothetical

It would have taken 6,036 voters switching from Liberal to Conservative — 9.6% of the 62,808 valid votes, 9.6 points — to change the result. No ballot was cast this way; this only moves votes between the top two.

Still Liberal by 12,070 votes. Actual margin: 12,070.

IVElection day versus advance

Only 53.0% of this riding's votes were cast at election-day polls. The rest were advance or special ballots.

On election day the Liberals took 51.7%, the Conservatives 40.3% and the New Democrats 6.5%; in advance and special ballots, 61.3%, 33.2% and 4.4%, in that order.

An association, not a cause. Voters who cast ballots before election day differed from those who turned out on the day. It does not say why. There is no poll-level turnout figure on this page: the elector count on a polling division includes people who voted in advance and were counted elsewhere.
